Chaeto Gro - Brightwell Aquatics

Grow stronger. Export more. Keep it balanced.

Brightwell ChaetoGro is a complete nutrient solution designed to fuel chaetomorpha growth in saltwater refugiums. Packed with essential elements like iron, cobalt, and molybdenum, it gives your macroalgae what it needs to grow fast, stay healthy, and consistently pull nutrients from your system.

In ultra-low nutrient systems, chaeto can stall out without proper supplementation. ChaetoGro helps keep growth steady, allowing your refugium to do its job—stabilizing nutrients and supporting a healthier, more natural reef.

The formula is clean and targeted. No added nitrates or phosphates, and completely safe for fish, corals, shrimp, and other invertebrates.

Dosing Instructions

Start with 5mL per 20 gallons twice weekly for the first two weeks, then adjust based on growth and system demand.

For more stable results, daily dosing is recommended. Dose 6 drops per 20 gallons per day and fine-tune after the first week.

For best performance, maintain at least 0.01 ppm phosphate and 3–5 ppm nitrate. If nutrients are too low, chaeto growth will slow regardless of dosing.
